Abstract Because cold-water coral ecosystems exist at relatively inaccessible
depths of 500–1,000 m, only a limited number of accurate maps have been produced for this resource. This chapter describes a combined acoustic survey
approach used to acquire high-spatial resolution (up to 0.5 m) maps from two
cold-water coral sites in the Straits of Florida. The approach consists of reconnaissance surveys using hull-mounted multi-beam systems, followed by deployment of multi-beam and side-scan sonar systems on an autonomous underwater
vehicle (AUV). The wide swath of the reconnaissance survey tools permitted
coverage of large areas, producing coarse (20 and 50 m) resolution maps that
identified coral-building mounds larger than 2,600 m
